It's a used MBP 2.33Ghz with matte display, purchased in late January. The previous owner was actually a Windows user who tried to switch but could never get used to the Mac system. So I'm assuming any use in it has been very light. I'm going to pick it up tomorrow so I was wondering if there was anything I should do to test the machine, to make sure nothing's wrong with it and everything's running at it's full potential. Any ideas? This will be the first laptop I've ever gotten too, so if there's anything in general I should know about taking care of it and assuring it's longevity, also if there's any essential widgets/shareware/freeware I should look out for, any advice would be greatly appreciated. Thanks!
